I just want to add my "me too" to this thread:

NetBSD 1.4 (WintelKiller) #111: Fri May  7 20:22:58 MEST 1999

If I use the ne0 card instead in the same 10BaseT network (and with the same
patchkabel) the number of Oerrs is ~0 and the collision rate is much lower.
So I doubt it's the physical network.

BTW: The (old) ep drivers in our 1.3.[1-3] Server run fine:
~0 Oerrs, 0 collisions in >14 months of use (3c905-TX, 3c900, switched
network). And I'm going to upgrade it this weekend to 1.4...
